Step 3: Create your path

Starting from hydrogen and going left to right fill in the orbital to equal the number of electrons, remembering that the s block fits 2 electrons, p block fits 6 electrons, d block fits 10 electrons, and f block fits 14 electrons

Watch an example

Step 2: Identify how many electrons the element has.

Remeber that electrons = protons in a neutral atom

There are 15 electrons in Phosphorus

Step 1: Find the element on the periodic table

Step 4: Fill the boxes

Fill the box acording to the electron configuration from step 3. Remember to fill in all empty boxes with up arrows befor switching to down arrows. s block has 1 box, p block has 3 boxes, d block has 5 boxes, and f block has 7 boxes
